TROLLEY.

Specification of Letters Patent.

Patented Sept. 24,1907.

Application filed June 12,1907. Serial No. 378,536.

To all whom it may concern:

Be it known that I, WILLIAM MonoKEL, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Trolleys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to a fixture for trolleys for overhead wires that are used in distributing current to electric vehicles, and the object of the invention is to provide a series of rollers, laterally disposed before and behind the trolley-wheel that engages the under side of the wire for collecting the current, these laterally disposed wheels being concave on their peripheries, and being adapted to engage the sides of the trolley-wire, when the trolley itself swings from side to side, so as to avoid the jumping of the trolley from the wire.

A further object of the invention is to provide a fixture, of this kind, that provides the laterally disposed wheels or rollers on a frame that swings on the pivot of the trolley-wheel so that when a pull is applied, by means of the usual rope, to the trolley-wheel, the frame carrying the laterally disposed rollers is held horizontal, or approximately so, and the frame carrying the rollers being pivoted on the pivotal pin of the trolley, the laterally disposed rollers are withdrawn from the trolleywheel when the trolley itself. is being adjusted to or withdrawn from the wire.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a side view of my improved device, and Fig. 2 is an end view showing one half of the trolleywheel and the improved retainer in section. Fig. 3 is a top view of the device.

I illustrate, in the drawings, any usual construction of trolley-pole 10 that has the side wings maln'ng up the frame 11 which can be of any usual construction, and between these wings 11, making up the frame, is a trolley-wheel 12 which rolls on the under side of a wire 13 having a concave periphery so as'to allow a slight side swinging of the wheel on the wire. The wheel is loosely mounted on a shaft 14, which itself is loosely mounted so as to swing in the frame. In a slotted recess, in each end of the shaft 14, is arranged a lever 15 pivoted intermediate of its ends on a pin 16, and having the longitudinally extending bars 17 with theupturned ends 18.

On each upturned end, of each of the side frames or bars 17, is a roller 19, the pair of rollers before, and the pair of rollers behind the trolley-wheel being arranged opposite to each other so as to bear about on the same point on the trolley-wire. The rollers 19 have concave peripheries, and are spaced so as to provide for their not normally engaging the sides of the trolley-Wire 13, but engaging the sides of the wire when too much side motion of the trolley-wheel takes place, thus preventing the wheel jumping from the wire. The lower end of each of the levers 15 is formed into an eye 20 into which is secured a loop 21, of rope or similar material, which is secured in any suitable manner to the cord 22 which is used to manipulate the trolley-arm to place the wheel.

It will be understood, from the drawing, that when the cord 22 is pulled to place or remove the trolleywheel, the lower ends of the levers 15 will be drawn downward and inward, and the rollers 19 will be pulled away from the wire. This pulling on the cord 22 also causes the rollers 19 to be held in a horizontal position as they were when engaging the wire, due to the pin 14 being loosely mounted in the side frames 11. Springs 23 connect the opposite upturned ends 18 of the bars 17 so as to normally replace the rollers 19 and keep them in their normally operative positions, shown in Fig. 2. The inner edge 24, of each lever 15, is adapted, when in normal position, to engage the inner end of the recess in the end of the pin 14 to act as a stop for the inward move ment of the rollers 19 on that side of the trolley.

The rollers 19 are kept far enough apart, normally, to not interfere seriously with the supports for the trolleywire which are usually placed above the wire and suspend the wire beneath them, and if the rollers 19 d0 engage the supports, the springs 23 permit them to part sufficiently to pass the supports without being seriously obstructed.

Having thus described my invention, what I claim is 1. A trolley comprising a frame having a pin loosely arranged therein, a trolley-wheel arranged to revolve on the pin, side frames pivotally arranged in the ends of the pin having lateral rollers arranged on their ends to engage the sides of the trolley-wire, depending portios on the side frames with means for attaching a rope thereto, whereby when the rope is pulled the side frames with the lateral rollers are sustained approximately horizontal, and the lateral rollers are at the same time pulled apart, and means arranged to normally pull the lateral rollers together.

2. A trolley comprising a frame having a pin loosely arranged therein, a trolley-wheel arranged to revolve on the pin, side frames pivotally arranged in the ends of the pin having lateral rollers arranged on their ends to engage the sides of the trolley-wire, depending portions on the side frames with means for attaching a rope thereto, whereby when the rope is pulled the side frames with the lateral rollers are sustained approximately horizontal, and the lateral rollers are at the same time pulled apart, springs arranged to normally pull the lateral rollers together, and means for limiting the movement of the lateral rollers toward one another so that they will not touch.

3. A trolley comprising a frame having a pin loosely mounted therein, a trolley-wheel arranged to rotate on the pin, U-shaped side frames with laterally arranged rollers on the ends, a central depending lever on each side frame, each lever being pivotally arranged in one end of the pin, means on the lower ends of the levers for lower ends of the levers for attaching a rope thereto, securing a rope thereto, and means tending to draw the means as a spring tending to normally draw the side (I-shaped frames towards the trolley-wire. frames with the lateral rollers toward the trolley-wire,
